Booster is softer and more voluminous than dip. It is therefore mainly used for baits, i.e. boilies, pellets, Method, Zig or PVA mixes, particles and the like. It is also designed to achieve the same flavor of the baiting boilie as the boilie you are fishing with. Baits can be poured with it for a longer period of time in advance, except for quickly disintegrating pellets. Boosters do not dissolve PVA materials, so you can also pour them on prepared PVA stockings shortly before casting. However, if you do this for a longer period of time in advance, be aware that the booster (especially with fish flavors) may contain ingredients that slow down the decomposition of PVA.
